Property managers lose more money to roofs they have not ranked than to roofs they have not replaced. A portfolio with ten buildings and no roof list spends its repair budget on whichever tenant called last. Every building you manage answers to the same winter, a 60 psf design snow and 115 mph of design wind in the city's current criteria, whatever edition it was built under. Send us the roll and the plans. We return a ranked list, a priced scope for each roof and the alternates on their own lines, so the owner decides what stays in.
The call: rank every roof before you fix any of them
The first deliverable is not a repair. It is a list. We walk each roof, take a core where the field warrants it, run a moisture survey on suspect areas and grade the roof: sound, watch, repair or replace. The grade comes with a cost range and a remaining-life estimate.
With ten grades in hand, a manager can build a budget. The worst roof goes first. A roof graded watch gets a spring and fall visit. A roof graded sound gets left alone. The list costs far less than a single emergency tear-off, and it turns a pile of tenant complaints into a plan the owner can approve. It also gives the manager a standing answer for the next tenant who asks when the roof over their suite will be looked at: the date is on the list, with the grade and the reason beside it.
Grade by evidence. A roof graded replace has a core result with wet insulation behind it. A roof graded watch has a moisture reading and a date to look again. A roof graded sound has photographs of its seams. Owners trust a list when each grade has a reason attached, and a lender reading the file sees the same reasons.
What it costs: tenant complaints, truck rolls and rework
The hidden cost on a managed portfolio is the repeat visit. A leak patched without a moisture survey comes back. A roof repaired by three vendors in three years carries three different products and no record. Each call costs a truck roll, a tenant conversation and sometimes a rent concession. Add them up across a year and the one-off calls often exceed the cost of a program. The only way to know is to track the calls by building, and the manager who does that usually discovers that two roofs account for most of the spend.
Price the program, not the call. A set annual visit per building, a standing price for common repairs and a reserve for the roofs graded repair or replace. We show the owner the annual number next to the history of one-off calls, so the comparison is on paper. Our preventive roof maintenance visits use the same checklist at every building, so findings are comparable.
What the code sheet says: one sheet, many buildings
The city sheet requires ice barrier underlayment, rates weathering as severe and sits under the statewide 2018 International Building Code. Prairie buildings answer to the same sheet, and the snow grows heavier eastward, from about 59 inches a year at Post Falls to roughly 76 at Wallace.
For a manager, the sheet sets what a replacement must meet. It also sets what a recover must carry. Two feet of wet snow on a flat roof is a serious load. We check the framing before any recover and price the check as a line. Where the record shows that a building was built before the current criteria, the check matters more, because older framing was often designed to a lighter load. An engineer reviews anything that looks stressed, and the result goes in the building file.
Where it fails first: curbs, drains and tenant-added units
On managed buildings, the first failures are rooftop-unit curbs, drains that freeze and penetrations added by tenants without notice. A tenant who adds a unit adds a hole. A drain that stays iced all January backs water against the parapet.
Ask for a roof-access rule in every lease: notice before any rooftop work, a log of who goes up and a requirement to use walkway pads. Our rooftop equipment curbs and supports work rebuilds failed curbs with flashing above the drift line, and the numbered roof diagram ties each curb to a unit so the cost goes to the right place. Common-area maintenance reconciliations work better when the roof invoice names the curb, the unit and the cause. A tenant who sees that their unit's flashing failed is less likely to dispute the charge.
Alternates: tapered insulation, walkway pads and a longer term
Break out what the owner may want to add or drop. Tapered insulation to cure a pond. Walkway pads on the service routes. A cover board for hail and foot traffic. A heavier edge for wind. Each is a priced alternate with a one-sentence tradeoff. We name which one we would buy for each building, and the owner can overrule us without penalty. A manager reporting to an owner needs to show that options were considered, and the priced alternates are that record.
Managers of mixed portfolios see the same logic across property types. An owner who holds for a set period, as investors and REITs do, lets the hold period set how much to spend, and a storm loss turns the roof file into insurance and restoration evidence as much as a repair record.
Schedule and snow window: book the portfolio in winter
The dry window on the Prairie is short. A manager with five roofs to do needs a crew calendar, not five separate bids. Book in winter, order material at award and stage the work so buildings in Post Falls, Hayden and Coeur d'Alene fall on one mobilization where the routes allow. A big wind is the case we plan the edges against. We tie down open edges at every shift end and price the temporary protection in the base, so a windy night during a tear-off does not become a claim.
Closeout: one record per building, one list for the portfolio
Each building gets its own file of seam, flashing and drain photos, a roof diagram, the punch list and a maintenance calendar. The portfolio gets a single list that updates after each visit. That list is what a lender, an insurer or a buyer asks for. Our multi-site roof programs keep it current. When an owner changes managers, the list changes hands too, and the new manager starts with facts instead of a stack of old invoices.
Commercial Roofing Questions
Do I need a roof list if I have not had a leak?
Yes. The list shows which roofs are close to failure before they leak, so the budget follows risk instead of complaints. A walk and a few cores per building is enough to start.
How do we stop tenants from damaging the roof?
A lease clause for notice, a log of roof access and walkway pads on service routes. Price a curb detail for every added unit.
What does a ranked list cost compared with one emergency tear-off?
Far less. The survey is a small fraction of a single unplanned replacement, and it prevents several. We put the numbers side by side so the comparison is on paper.
Can one crew serve buildings in different towns?
Yes. We group by route, so one mobilization covers Post Falls, Hayden and Coeur d'Alene sites where the schedule allows.
What records does the owner receive?
Photographs, a numbered roof diagram, core results, a punch list and a maintenance calendar for each building. The same package works for a lender or a buyer.
